Changing the offsets in (THUM.exe) the software included with the THUM does not affect the readings in Gagepack or other software using the THUM DLL. Gagepack is talking directly to the THUM.
Version 1.0.0.5 and above of the THUM.dll allows you to enter offsets into a text file that be used to adjust the readings taken from the THUM from any application that uses the THUM.dll.
Do a search for the THUM.dll on your system and look at the file properties to see the version of the file? If it is version 1.0.0.5 then you can add offsets to a file that the THUM.dll will use.
An offset file stored at %ProgramData%\THUM in THUM_Offsets.ini provides offset values for internal temperature sensor, external temperature sensor, and relative humidity sensor values. Temperature offsets are in Degrees Celsius. These offsets may be positive or negative. If the offset file does not exist, it is created upon any DLL function call that reads values from the sensors. The application using THUM.DLL must be restarted to pick up offset modifications.
If the THUM DLL on your system is an older version, please contact Practical Design Group and we will send you a newer version.
To replace the THUM DLL:
1. Log into the computer as an administrator
2. Rename the current dll, so that you can go back to it if needed.
3. Extract the dll file from the attached zip and put in the same folder as the current thum.dll. If Gagepack is installed in c:\program files (x86) you will use the 32bit version of the dll. Otherwise use the 64 bit version of the dll. You only need to put the dll file in the folder.
4. Start Gagetrack and take a reading to ensure the new folder and offset file is created
5. An offset file THUM_Offsets.ini stored at %ProgramData%\THUM provides offset values for internal temperature sensor, external temperature sensor, and relative humidity sensor values. Temperature offsets are in Degrees Celsius. These offsets may be positive or negative. If the offset file does not exist, it is created upon any DLL function call that reads values from the sensors. The application using THUM.DLL must be restarted to pick up offset modifications.
